Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997644, here are decompositions:

7 + 997637 = 997644
17 + 997627 = 997644
47 + 997597 = 997644
61 + 997583 = 997644
71 + 997573 = 997644
97 + 997547 = 997644
103 + 997541 = 997644
181 + 997463 = 997644

Showing the first eight; more decompositions exist.
